WATCH: First Harrowing Trailer for Kalief Browder Docuseries

Surveillance footage of Kalief Browder’s interactions within the criminal justice system—his intitial interrogation for allegedly stealing a backpack, his beating and solitary confinement at Rikers Island—feature alongside clips of his mother, Venida Browder, visiting the sites of painful memories in the new trailer for “TIME: The Kalief Browder Story.”

The Jay Z-produced docuseries explores Browder’s infamous three-year imprisonment without trial at the notorious New York City jail and the traumas he experienced during that time. Arrested at age 16, Browder endured violence from both correctional officers and fellow incarcerated individuals. He also spent a total of 400 days in solitary confinement. Browder and his mother fought for justice, generating enough outrage to compell New York City Mayor Bill de Blasio’s pledge to reform trial waiting periods for minors. Struggling in the aftermath of his time in jail, Browder committed suicide in 2015.

His mother, who died this year, describes those struggles in the trailer above. The series will premiere at next month’s Sundance Film Festival and air on Spike in March.
